Hey guys!I have made some quick test tonight and have something interesting to share.I have wound 4 layers of magnet bifi wire over a ferrite stick. I use the first layer as a classic "joule thief " as the primary for the oscillation and connect the rest of the 3 layers bifilar serie to have open end coil as Jack show us.

First try I have a poor output but it's completely lens free!!I have play a bit with my primary bifi coil and found that when I use it open (connect the oscillation to separate legs/wire of the bifi and leave it open) I have much more power at the output than when the primary is normal close coil! . It remind me the lorrie matchette device...

It remind me the lorrie matchette device as Danways said...

So this time I changed the drive mechanism to a push/pull board that I had builtfor another project. The oscillator capacitor is a bit large and limits my top-endfrequency to about 100kHz. I may switch that out and see what happens athigher frequency.

Still not seeing what I would call over-unity as yet, but I can easily drive the lampto normal brightness--remember this is still a coil that is open on the ends.

Instead of the two pieces of ferrite core, I made a 16-strand clump of weldingrod and inserted that. What's odd is with the core (top scopeshot) the lamp isless bright, system draws less amps and the core gets hot. With the coreremoved (lower scopeshot), lamp brightness is higher, but current draw goesup. Also notice the RMS voltage hasn't changed, but the brightness of thebulb is clearly evident. I state that because a lot of people assume higheroutput with a brighter bulb--not necessarily true for a filament bulb. Withoutchecking the current and phase angles, we'll just assume brightness level asan indicator of output power for now.

The blue trace in the scopeshots is one side of the push/pull digital signal soyou can see the approximate duty cycle and get a good reading of thefrequency. The jaggedness of the yellow output trace across the lamps tellsme the resonant frequency is probably quite a ways up the spectrum.

I should also note, when the lamp is shorted, current draw goes way up aswould be expected by any typically transformer arrangement. So even withthese open ended coils, impedance takes over and DC resistance no longermatters. Lenz effect is clearly present in this system. I do know it wouldsure mess with the heads of a lot of electricians--open DC circuit poweringa light bulb.

Well, we have a primary, pulsing. So far nothing special. Then we got there basicly two secondaries. Still nothing special!

Induction takes place, electrons are forced to move, regardless of wether these coils are connected to anything or not. There is tension at one end and pressure at the other end of each of these two. If we connect a load in series between these two, we allow a certain exchange of electrons between these two coils. However, the current will be highest at the loads contacts and lowest at the open ends, as if we move the center of a rubber band alternating towards the two fixed ends of it. In comparation, a normal output coil has the same current everywhere. All electrons are stressed the same and have the same freedom of movement.

This means, if we induce rather the open ends of the coils, then they will basicly perform like a shortened output coil, but if we induce the other ends instead (the ones connected to the lightbulb), then the unproportionally high current may perform better than any closed coil with no load attached. Overunity at this end of the coil.

Just some thoughts.

I currently moving, so all projects are on standby, hope to be back for tests asap.

BTW, Woopy, thanks for the video. Very impressive. These bugzippers draw only a few current, they run for hours with the two 1.5 V batteries. Output depends on sparkgap frequency, maybe 500 to 1500 V. But in the video, your 220V bild is flickering. I was wondering if it was flickering precisely like that, or whether the video framerate just caused a moiré pattern with the pulse frequency and in real it was shining continously / at the pulsed frequency?

This need more investigations!

Thank you Jack !!!

wistiti, I believe you have discovered induction by oscillating electric field, in other words induction by voltage pulsing! I think I know what is going on here, I try to explain it. In the coil capacitor system the magnetic field occurs outside the wire and it is in the direction of the wire. When coil capacitor is used as a primary in a rod core it creates magnetic flux that is a contained in the core. I say contained because I don’t know if the flux is circulating or pulsating, but it does not matter for now. Since contained flux is much more efficient than open loop flux more charge is induced in the copper nearby. As the electric field in the output coil is increased the magnetic field increases with it. So the lamp gets brighter as more energy can be pulled in from the ambient when the magnetic field is stronger. The pick up must be a coil capacitor as well. Single coil does not output anything as there is no voltage drop between coil ends. Charge is induced there but as the flux does not move across the coil the voltage is constant in every part of it, the coil will not output anything. When the pick up coil is a coil capacitor it does not matter ‘which way’ the charge gets induced there. Charge either moves from one end to another or charge density increases and decreases in the whole coil length. Either way the electric field is oscillating and creating the oscillating magnetic field which pulls in the energy. It would be interesting to see the waveform of the output coil pair when coil capacitor is used as a primary.

Induction by voltage pulsing gives us another remarkable benefit. The current draw from the source drops significantly, or maybe even close to zero if pulses occur both ways. The drive is now only pumping charge through a capacitor! I believe that finer the wire used in the primary coil capacitor the greater the induction effect. Turn offset optimization in the primary could also work in this case but I am not sure if it would have any effect when used in the output coils. But don’t take my word for it, these should be tested.

But there is more. The coil capacitor is pulling energy directly from the ambient and this energy flow is present in the primary also. I believe that it can be used. Add blocking diodes to free ends of the primary coil capacitor and use the capacitor, diode bridge with smoothing capacitor like you did in the output section. Perhaps there is enough hot electricity to make a self runner? Verify the voltage and amperage before making loop back so you don’t break anything. You could put blocking diodes in the output coils as well to increase output and later to prevent frying of the coils. I think that the output power can be controlled by the voltage of the pulse and by the frequency of pulses. To study the effects of these two variables would be the next logical step.

Induction by voltage pulsing is a great improvement to the basic system and it opens up new possibilities. Instead of seeking for resonance that could be well below 100 kHz the system could just be voltage pulsed at e.g. one MHz, or even higher. This depends on the limits of the core with voltage pulsing, perhaps higher frequencies can be used than core specs allow. There could be a sweet spot in the magnetic flux also. If magnetic flux is wave like then it will have resonance just like charge does. If voltage pulsing allows the use of higher frequencies then it could open the gate to resonant magnetic flux.

------------Dog-One, put blocking diodes in the output coil pair: --<-- load -->--, this will make sure that charge is not moving in a closed loop in your system and you get lenzless behavior. I have shorted the output in my tests and it had no effect on the input. I was using closed loop core and the collector coils were separated from the primary or primary was on top of secondaries. I did the shorting test with and without diodes with current limiter bulb on. One possibility is that your coils are leaking. If so then you should see electric current, or energy flow between same ends of output coil pair. To prevent leaking to occur the loose ends should be connected together using maybe two mm air gap or use blocking diodes before coils are used for the first time. Coils do fry easily and instantly if this is not done and by looking at the scope shots you have provided it could have happened to your system. There were over one kilovolt spikes in the first scope shot, do you think the insulation in the wire that was used can withstand this amount of pressure ? Your output coils are hidden so you cannot see the white dots which occur when the coil is fried. Coil frying is a real nuisance, I should have stressed about it more. It happened to me many times until I started to use blocking diodes. I fried all my test systems except the last one, lol.

You seem to be right. I have do some more quick testing and am able to charge a capacitor beside the blocking diode at the open end of the primary. Much more interesting, I find I could charge ( at the same rate) 2 separate circuits from this open secondary!! All that with no apparent effect on the input power...

I don't quite understand how it really work but it does. Power input seem not to be important here... Until now I find just voltage and frequency have effect.

Hi all, hi wistiti, after seeing what you are doing, i am now going to give it a go also.Going to use the ferrite tubes i have here and wind a few bifilar layers and make the first one an oscillator.Seems interesting that you are getting better output while using an open primary oscillator coil. Not sure i comprehend how the joule thief is still oscillating like that and i don't see any transistor and such in your circuit.Anyway, sounds like your transmitting something from that open primary.peace love light

Hi Sky!Nice to ear you will try it too! My primary is not a joule thief... ( I try it first) Now I use a radiant oscillator, from Sultech, I have build as the primary source. I connect it on the primary coil who is open... Hope to be clear... not sure...

I think the best primary power is one who can deliver hv and variable frequency... but it need more testing (that's why am happy you be here!!) Since now with my little research I found amp is not much a matter... It seems all about Voltage and frequency Like Jack have said.

In my last test I use just one leg of the primary to extract power. (as Jack suggest) I found I can have much power when grounding (maybe antenna will also work) the other leg of the fwbr.

Here is a quick tip. Its not about Jack's circuit but about the AV plug.The AV plug must end quickly at the capacitor. That's all No antennas, wires, leads to meters etc after the plug. It must also be a foot or more above ground. Its best to use LEDs , filament bulbs, etc as you can't measure the v on a small cap with a 1OM meter all that well when the circuit is off. If you have any wires at all after the AV plug you are capacitely coupling to earth , or just to the free space capacitance of the metal object, drawing big current thru the wire to the AV plug . Perhaps it don't matter with Jack's free energy, but if you do it with a freq gen, it will suck power out of it.

Hi Promodoro.Yes I haved realised that the "excited" legs go to the half of the bridge (AV plug) but the strange thing here is this "excited" leg are blocked by a diode BEFORE the av plug... So normally nothing should reach the av plug.....

I did not know about the rest of the reference you give about how to optimize the av plug output.... Interesting!Thank you!

The diode that blocks the av plug could have some capacitance, be too slow for the dV/dt or suffer some avalanche or zener breakdown. These factors and perhaps some I have not thought of need to be looked at first. Another factor is that a coil opened at both ends excited by another can pass large currents if a small length of wire is attached to the ends or even just one end. Its easy to show this using a small Tesla coil with both ends of the secondary not grounded. If a small filament bulb has one terminal attached to just one end of the secondary, and a short wire is attached to the other terminal of the bulb, just into space, enough current can flow to make the filament glow, even with a totally insulated wire to stop a corona discharge. Electrons are pumped to and fro the dangling wire, which has some capacitance. Again, this doesn't mean Jacks circuit isn't doing something special, but Im trying to explain to you the behavior of high voltage spikes or high frequency signals on single ended wires. Tesla explained this when he lit his famous bulbs with one wire

As I mentioned a couple of times before, any diode is conductive in both ways for the very first few nanosecs or microsecs of a Pulse. As the open secondary is basicly two open secondaries, connected by a load, the actual spike is very short, as it penerates even a HF schottky diode both ways.

Shorting the open secondary (instead of a lightbulb load) will simply make it one normal secondary with no load attached, no surprise there.

Bringing the open ends close together, so a sparkgap is taking place, clearly showed in my (1000vdc on primary pulse) experiment that the secondary in fact has high voltage, maybe 1 to 2 kV. Yet, the LED was not fried, but when I recently tested the DC resistance of this blue 100mA 3V LED (5 LEDs in parallel internally), my meter showed something like 5 megaohm, I think that is not normal. However, it is still working.

No matter how low the resistance of the load is you connect to this open ends secondary, the secondary will always be like a standard secondary with absolutely no load attached, and that is the beaity of it.

I think we should therefor concentrate on a secondary with a huge amount of turns and copper, induced by a very efficient inductive coupling design.
